Introduction
JA: I ran into some problem in trying to dis-equivocate a number of the terms in the first paragraph. Somebody redirected mental stimulus to cognition, which is too broad for what's intended there -- rather than list the whole panoply from sensation to perception to cognition, I just took a sample out of the middle, and dabbed to stimulation to cover the raw stimulus aspect, for now. And representation gives a disambig page, the closest of which items would ordinarily be knowledge representation, but that page as currently written is a bit too specific to library science. I will work on a more generic representation article as a separate issue. Jon Awbrey 14:46, 17 January 2006 (UTC)
The controversial claims of Roy Frieden
I am concerned about edits related to the controversial claims of B. Roy Frieden (Prof. Em. of Optical Sciences at the University of Arizona). As an anon, he has edited this and other articles as the data.optics.arizona.edu anon:
- 150.135.248.180 (talk · contribs)
- 16 June 2006 states controversial claims as established fact in Extreme physical information
- 16 June 2006 adds "Physics actually derives out of information, through the principle of Extreme physical information " to Information.
- 6 June 2006: adds cites of his papers to Extreme physical information
- 23 May 2006 adds uncritical description of his own work in Lagrangian and uncritically cites his own controversial book
- 20 May 2005 confesses IRL identity
- 22 October 2004 attributes the uncertainty principle to the Cramer-Rao inequality, which is potentially misleading
- 21 October 2004 adds uncritical mention of his controversial claim that the Maxwell-Boltzmann distribution can be obtained via his "method"
- 21 October 2004 adds uncritical mention of his controversial claim that the Klein-Gordon equation can be "derived" via his "method"
- 150.135.248.126 (talk · contribs)
- 9 September 2004 adds uncritical description of his work to Fisher information
- 8 September 2004 adds uncritical description of his highly dubious claim that EPI is a general approach to physics to Physical information
- 16 August 2004 confesses IRL identity
- 13 August 2004 creates uncritical account of his work in new article, Extreme physical information
- 11 August 2004 creates his own wikibiostub, B Roy Frieden
It is important that mention of Frieden's work in the WP clarify that his claims are by no means universally accepted by his peers. I am very disturbed that he is stating his claims as established fact, when they are actually by no means universally accepted:
- Binder, Philippe M. (2000). "Physics from Fisher Information: A Unification (a review)". American Journal of Physics. 68: 1064–1065. (favorable)
- Kibble, T. W. B. (1999). "Physics from Fisher Information: A Unification (a review)". Contemporary Physics. 40: 1999. (the reviewer has some positive comments but concludes that Frieden's work is "misguided")
- Case, James (2000). "An Unexpected Union---Physics and Fisher Information". SIAM News. July 17. eprint (highly favorable)
- Matthews, Robert (1999). "Physics and Fisher Information (a review)". New Scientist. January. unauthorized electronic reprint
- Physics from Fisher Information: A Unification (a review) from Cosma Shalizi (Computer Science, University of Michigan) (highly critical)
- Physics from Fisher Information (a review) from R. F. Streater (Mathematics, Kings College, London) (highly critical)
- Physics from Fisher Information thread from sci.physics.research, May 1999 (mostly critical)
- Fisher Information - Frieden unification Of Physics thread from sci.physics.research, October 1999 (mostly critical)

Comments
In the section "Information as a message", the second paragraph states the following,
...in requiring the existence of a definite sender, the "information as a message" model does not attach any significance to the idea that information is something that can be extracted from an environment, e.g., through observation, reading or measurement.
This statement is misleading in its implication of a "sender" as being separate from the environment. The concept of a "sender" or "source" has no specification to who or what is sending or supplying information. Therefore, the implication of the above statement is unjustified and thus leads to an inconsistency. This statement should either be clarified or revised.

This image is no good?
Sorry, I thought that this was a novel idea for an image for the "information," article? I added it and somebody reverted it. If the general consensus is that it's a bad idea, I'll have the iamge deleted, but I thought I'd just ask, as I think articles without images are ugly. Robocracy 06:57, 21 November 2006 (UTC)
- What does 'The word, "Wikipedia", in binary' mean? I'm guessing that it's the binary representation of the ASCII codes for "Wikipedia", but it makes no sense as it is (and I don't think that the commas belong there either). --66.81.125.112 21:37, 22 December 2006 (UTC)
- In addition to agreeing with the previous comment, the gradient is a little annoying. Understandably, one would like to have a little stylistic flair, but the rendering in this image clearly draws too much attention to itself and merits at least a change to be a little more subdued. dr.ef.tymac 16:47, 6 February 2007 (UTC)
- i came to this talk page precisely to see if there was a discussion on the picture, as i am not in favor of it being here. I looked at the article's contents to see if it could be moved down from the top of the page, but couldn't find any suitable spot. So, i say: remove. --Jerome Potts (talk) 23:34, 21 November 2007 (UTC)
Standard definition of Information from ISO
Wiener information definition counter: The information is the information, the information is the material, the energy, the information and the attribute indication (identification).
Counter Shannon information definition: The information is definite increase —Preceding unsigned comment added by 124.254.23.217 (talk) 05:02, 1 October 2008 (UTC)
From ISO TR-9007 from 1983 and 1986
Definition of Information: Any kind of knowledge about things, facts, concepts, etc. of a universe of dis-course that is exchangeable among users. Although exchangeable information necessarily will have a representation form to make it communicable, it is the interpretation of this representation (the meaning ) that is relevant in the first place.
I do not see this definition on this page and would like to introduce it.

I would go further back to look for a definition... "Information is the minimum required by the user to make a decision, it is the result of a structured query on data" One mans data is another mans information and vice versa, data is produced constantly but it is in the user and the questions the user asks that it becomes information... 87.102.44.114 02:06, 5 February 2007 (UTC)
- This is not definition, it is just handwaving. ISO, a body of engineers, is incompetent in such a basic scientific topic as the definition of information. Information should be rigorously defined by the SI comitte, either as an abstract construct, like the seconds of time derive from the speed of light or as an artifact, like the platinum master kilogramm kept under glass cage in Paris.
- As long as you fail to show me the SI "master etalon" of information, I dare to say infomation does not exist per se or maybe it is just our cloudly commodity perception of multiple phenomena, which we cannot yet differentiate due to the weakness of human senses. 91.83.17.127 (talk) 22:03, 22 June 2008 (UTC)
- Nonsense. If that first really is an ISO defintion, and it's sourced, it should be in the article. If it's just commentary on some other topic, it probably shouldn't be in the article. I'd need to look at the reference to be sure. — Arthur Rubin (talk) 06:38, 23 June 2008 (UTC)
Major Cleanup
I see quite a few problems with this article, quick example:
If you accept that information can be defined merely as a pattern, does it not follow that neither utility nor meaning are necessary components of information? Surely a distinction must be made between raw unprocessed data and information which possesses utility, value or some quantum of meaning. Information may indeed be characterised as a pattern; it is a necessary condition, but not sufficient.
The first part has a triple negative and makes no sense. That aside, information as a pattern has nothing to do with utility. Information doesn't require utility. Also, what is "a quantum of meaning" anyway?
Information can be a tough article, but we can do it. 76.23.14.222 08:22, 9 April 2007 (UTC)
To me it appears that information more than merely a pattern. Wshen we write "Tree" the writing is merely a pattern. The pattern will differ for different laguages but the information is the same.Obviously a code of translation is required for converting a pattern into information. Ultimately information can only reside as pattern (coupled with a translation code) in the four dimentional wosrld we know of. Where exactly information resides is a mystery.

New article request
Hi there, I'd like to suggest a new article on the full history of information handling/management/techonology (details). I'm not knowledgeable enough to do it myself, but contributors here probably are. Thanks, JackyR | Talk 18:04, 4 December 2007 (UTC)
information precision
inverse Shannon’s information definition: information is increase of determinacy.
Wiener information definition counter: The information is the information, the information is the material, the energy, the information and the attribute indication . Deng‘s definations.
information precision should be defined in this article. I hope that someone can do so. Jackzhp (talk) 18:58, 13 January 2008 (UTC)
I would like to add a definition that information is work done on matter by energy. Examples abound in biochemistry. Anabolic chemical reaction require energy to build complex molecule (like protein enzymes from amino acids). Enzyme systems are thus built up during growth and development. These systems contain large amounts of information that provide function. During atrophy or severe illness, these molecules and information can be broken down, releasing energy for heat or use by ATP systems. The thermodynamis (calories in/calories out) have been well worked out. To argue that this information is work is thus supported by thermodynamic consideration.
The rejection of this addition on grounds that it sounds like intelligent design failed to understand this biochemistry as science (verifiable by empiric methods) and instead supposed it is religous in nature. I have no such intent. I consider the formation of matter into shapes and functions that provide information part of natural (not supernatural) evolution. Khobler (talk) 02:48, 17 August 2008 (UTC)
- We need a source for the information that that particular structuring is called information, as it's not quite the same as other definitions. I am sorry about the Intelligent Design reference, but the concept of "conservation of information" applied to irreducible complexity is exactly the ID argument.
- Also, what you wrote seems confused as to whether the "information" is complexity or energy density. It is not necessarily the case that more complex structures have more stored energy. — Arthur Rubin (talk) 03:16, 17 August 2008 (UTC)
Thanks. Apology accepted...I see your point. I'll have to dig up a reference for Ludwig Boltzmann's often quoted statement that entropy is the opposite of information. I am suggesting a definition of information in the physcical universe as properties (color, shape, etc.,) and functions evident from various formations of matter shaped by energy (Big Bang and since). Some of this will have meaning and usefullness to humans, but that is irrelevant to the idea that this information and function is in the physical world. In that sense, complexity can be related to information as implied by Boltzmann. Khobler (talk) 13:24, 17 August 2008 (UTC)
Bias and/or lack of sources in "Information as an influence which leads to a transformation"
Some people argue that the fact that DNA records meaningful information means life must have come about because of a conscious mind, the exact opposite statement of what this article says —Preceding unsigned comment added by 75.11.13.28 (talk) 18:17, 9 September 2008 (UTC)
Information Booth
An editor used the term "information booth" on another Wiki page. Perhaps this term should somehow be included?--MurderWatcher1 (talk) 17:36, 18 December 2008 (UTC)
What is Information?
Dear all,
This article reflects general confusion about what is information. Although this page should not be used to discuss the topic, we have to reach a sort of agreement to start cleaning up the mess the article is currently in.
First of all, Wiener changed the sign in Shannon’s equations turning information entropy into information. Consequently, we have the whole industry and quite a multitude talking about “information” rather than patterns. And the fact is that our machines work with patterns without a meaning. And humans need to tell to the machine how to interpret a pattern. If a programmer makes a mistake and interprets “abcd” string as 32 bit integer, for example, the program will spit out a lot of nonsense. In short, “gqvklurx” that would be “highly informative” in IT cannot be considered seriously when we are trying to explain what is information. I think that all of IT related uses of term information need to be disambiguated with this pointed out.
That said, each pattern is potential information. However, if we cannot assign a meaning to a pattern, it remains what it was - a pattern. For example, Etruscan inscriptions are definitely patterns, but they do not give us a clue what they say. Etruscan inscriptions did mean something to Etruscans long time ago, but they mean nothing to us. And the meaning is not like a bird sitting on a branch waiting for us to catch it.
Kolmogorov did an excellent effort to mathematically describe (the impact of) information, although he was mostly looking at patterns (bit-strings). His major premise was that information shortens bit-strings required to describe something, so he was looking at mathematical ways that shorten bit-strings.
This “shortening” is at the core of information. Patterns with meanings about something we already know are not informative. Patterns with meanings we do not know and that do not impact other stuff we already know are of little, if any, informative value. Only patterns with meanings that challenge stuff we already know can be informative.
Only a pattern with a meaning that tells us that the sun doesn’t go around earth, but rather other way around can be informative. Ptolemaic system could have been made to work even today, but Copernicus, Galileo and Kepler made things much simpler, i.e. shorter.
I hope that we can reach an agreement here.

Back to Basics - A Proposal
I see some good work on information to date, but I also see the aftermath of too many comment wars. Resulting scope is too broad and somewhat irregular. So let's attack it with an open mind, and get back to basics. My suggestions:
- open with a basic, plain-language defintion that is based on concepts of "representation" and "abstraction", intuitive enough for the vast majority of readers
- introduce data as a syn. of information
- introduce knowledge as a product of information plus context, citing T.Stewart (2001)
- introduce data relationships and metadata as a means by which information can be further described, possibly quoting Codd
- remove scientific/academia sections with refs to math, entropy, physics in favor of existing information theory posts, which already cover the material thoroughly
- keep entymology
- keep list of "related terms" but in a subsection - it's supporting, not primary
- condense discussion of patterns, messaging, records and sensory aspects into less scientific treatment, to make material more intuitive and accessible; would keep some scientific references in, but only where they can be wiki link'd elsewhere
- make obvious connections to the modern commercial workplace, linking to information technology and knowledge management practices
I'm not going to bite this off without a general mandate to proceed, as I see a risk of pushback. Just my two cents, but I think Wikipedia needs information to be a strong post. Let me know.
JonesC-NC (talk) 04:02, 9 April 2009 (UTC)
- Whatever we do, it should be based on sources; either follow the general development of a source or two, or lay out alternative meanings backed by alternative sources. It's not obvious whether the approach you describe above is based on sources, or whether it's your own organization based on your own conceptions. We've tried that approach already; it can't really make a lot of people happy, or survive the many different viewpoints that will warp it around if it's not tied down by sources. Dicklyon (talk) 04:24, 9 April 2009 (UTC)
- It would all be supported by sources; I guess you're saying anything posted that is coherent, well written and supported by sources has a chance of survival? If so, fair enough, let me see what I can come up with, maybe on an incremental basis (section at a time) JonesC-NC (talk) 13:33, 9 April 2009 (UTC)
- Yes, that's sort of what I'm saying; also, though, that it helps if the overall organization can be justified in terms of a source, when you're doing a major re-org. Not necessary, but can help. Dicklyon (talk) 14:46, 9 April 2009 (UTC)
